G-Power takes the M6 to a whole new level. First check out (here) what they did to the M5. If you have a M6 and it’s not fast enough, we have a solution. The German tuning house can upgrade your 507hp V10 to an astonishing 635hp. 0 to 100 km/h in just 4.6 seconds, 0 to 200 km/h in 11.9 seconds and 0 to 300 km/h in 34,5 seconds. I find the 0-60 time to be a little off, a regular M6 is supposed to be in the low 4′s and an extra 128hp should make it a lot faster. Regardless the car is just amazing.
